CALGARY, ALBERTA--(Marketwire - July 12, 2012) - Canadian Utilities Limited announced today that its Board of Directors has approved the implementation of a Dividend Reinvestment Plan (DRIP).

The DRIP allows eligible Class A and Class B shareholders of Canadian Utilities Limited to reinvest all or a specified portion of their dividends, as and when declared by the Board of Directors, in additional Class A non-voting shares. It is effective with the quarterly dividend payment in September to Class A and Class B shareholders of record as of August 10, 2012.

Shares purchased under the DRIP will be new Class A shares issued from treasury. The shares will be issued at a two per cent discount to the volume weighted average price of the Class A shares traded on the Toronto Stock Exchange during the last five qualifying trading days preceding the dividend payment date.

Participation in the DRIP for eligible Class A and Class B shareholders depends on whether the shareholder is a registered shareholder or a beneficial shareholder. A registered shareholder holds shares directly with Canadian Utilities' registrar and transfer agent, CIBC Mellon Trust Company, and the shareholder's name appears on the share certificate. Eligible registered shareholders may enrol in the DRIP directly by submitting a completed enrolment form to CIBC Mellon Trust Company. Canadian Stock Transfer Company Inc. acts as administrative agent for CIBC Mellon Trust Company.

A beneficial shareholder (or non-registered shareholder) holds shares through a nominee (usually a bank, broker or trust company). Eligible beneficial shareholders who wish to participate in the DRIP cannot enrol directly but may participate indirectly via the broker, investment dealer, financial institution or other nominee through which they hold their Class A and/or Class B shares. Beneficial shareholders are advised to contact their broker, financial institution or other nominee for details on how to participate in the DRIP and to provide appropriate instructions.

Copies of the complete DRIP, a related questions and answers document and the enrolment form can be found at www.canadianutilities.com and the Canadian Stock Transfer Company Inc. website at www.canstockta.com. Eligible shareholders are encouraged to read the full DRIP to understand participation rules and other terms and conditions of the DRIP, including, but not limited to, Canadian Utilities' right to amend, suspend or terminate the DRIP and eligibility restrictions that only allow participation by Canadian and Australian residents that are not United States persons (as defined by U.S. federal securities laws).

Participation in the DRIP does not relieve shareholders of any liability for taxes that may be payable in respect of cash dividends that are reinvested pursuant to the DRIP. Shareholders interested in participating in the DRIP should consult their own tax advisors as to the tax consequences of doing so in their particular circumstances.

ATCO Ltd., as controlling shareholder of Canadian Utilities, intends to participate in the DRIP to maintain its controlling interest in the company.
